Check out bsdiff and bspatch (website, manpage, paper, GitHub fork).

To install this tool:

  • Windows: Download and extract this package. You will also need a copy of bzip2.exe in PATH; download that from the "Binaries" link here.
  • macOS: Install Homebrew and use it to install bsdiff.
  • Linux: Use your package manager to install bsdiff.
